I Became A Thief Who Steals Overpowered Skills

The novel is good, but I stopped at chapter 58 because I hate inconsistency, especially in emotions. What do I mean? In chapter 58, Crouch says that he was in love with a girl named Irina, but then he says that his ability to erase emotions erased his feelings for her. That doesn’t make sense, because he’s already in love with his fiancée, and his feelings haven’t disappeared. I didn’t notice any erasure throughout chapter 57, and then suddenly in chapter 58 he says that the curse erased his feelings. It doesn’t make sense.
If anyone has an explanation for this, please let me know.
